Secure MISO-NOMA Transmission With Artificial Noise [PDF]
IEEE Transactions on Vehicular Technology, 2018 This correspondence studies a new secrecy beamforming (SBF) scheme for multiple-input single-output non-orthogonal multiple access (MISO-NOMA) systems. In particular, the proposed SBF scheme efficiently exploits artificial noise to protect the confidential information of two NOMA assisted legitimate users, such that only the eavesdropper's channel is ...

Artificial neural net based noise cancellor [PDF]
ACE '90. Proceedings of [XVI Annual Convention and Exhibition of the IEEE In India], 2005 This paper presents a new method for noise cancellation with an Artificial Neural Network. The network used is a feedforward one with three layers. The backpropagation and Stastical Cauchy's learning algorithms are employed for adaptation of the internal parameters of the network.
